If there is no victim on the top bunk, what should you do with the roof hatch during ventilation?

• A. Stow the roof hatch on the top bunk.
• B. Remove the roof hatch from the aircraft.
• C. Leave the hatch open.
• D. Close the roof hatch and seal the opening.

Answer: (A)

During ventilation, control of air movement and keeping used equipment secured is essential. If there’s no victim on the top bunk, you don’t need the roof hatch actively contributing to airflow in that area. Stowing the hatch on the top bunk secures it out of the interior path, prevents it from swinging or being damaged, and keeps the hatch ready for quick re-deployment if needed later. Leaving it open would create an uncontrolled air path that could draw smoke or heat toward the upper area or responders, and removing or sealing it would hinder ventilation. Stowing it balances safety with the ongoing need to vent effectively.
